Definitions
- the present disclosure generally relates to a method of using a laser line generator tool of a pipe machining apparatus and, more particularly, to a method of using a laser line generator tool of a pipe machining apparatus configured to machine large diameter pipes.
- One such process includes cutting pipes.
- Large diameter pipes may be cut with a split frame pipe machining apparatus, which includes two frame halves that surround the pipe from respective sides and are coupled together around the pipe.
- Such a pipe machining apparatus includes a cutting tool that encircles the pipe and moves toward the pipe in small increments during a cutting process in order to slowly cut into the pipe. Eventually, after many small increments of adjustment toward the pipe, the pipe will be completely cut.
- a method of using a pipe machining apparatus includes providing a frame capable of being mounted onto a pipe, a tool carrier coupled to and movable relative to the frame, a tool support coupled to and movable with the tool carrier relative to the frame, and a laser line generator tool mounted on and movable with the tool support.
- the laser line generator tool images a laser light onto the pipe to align with a mark(s) on the pipe which denotes a proper cut line around the pipe.
- the apparatus can be repositioned relative to the pipe in order to enable an operator to properly position the apparatus on the pipe prior to a cutting operation.
- FIG. 1 depicts a top front perspective view of an exemplary pipe machining apparatus coupled to a pipe having a laser line generator tool mounted thereon;
- FIG. 2 depicts a front view of the pipe machining apparatus, with a portion thereof broken away to show internal components of the pipe machining apparatus;
- FIG. 3 depicts a front view of an exemplary tool support of the pipe machining apparatus, with the tool support illustrated in an engaged position;
- FIG. 4 depicts a top front perspective view of the tool support of FIG. 3 ;
- FIG. 5 depicts an exploded top front perspective view of the tool support of FIG. 3 ;
- FIG. 6 depicts a front plan view of the tool support of FIG. 3 ;
- FIG. 7 depicts a top front perspective view of the laser line generator tool.
- FIGS. 1 and 2 there is shown one exemplary embodiment of a pipe machining apparatus 20 adapted to machine pipes P of varying diameters.
- the apparatus 20 completely cuts through the pipe P.
- the apparatus 20 prepares an end of a pipe P for coupling to another pipe.
- the apparatus 20 both completely cuts and prepares a pipe P for coupling to another pipe.
- the apparatus 20 is formed of two joined-together semicircular sections 24 A, 24 B and includes a frame 28 and a tool carrier 32 .
- the two sections 24 A, 24 B together comprise the frame 28 and the tool carrier 32 such that a first portion of the frame 28 and a first portion of the tool carrier 32 is included in one section 24 A and a second portion of the frame 28 and a second portion of the tool carrier 32 is included in the other section 24 B.
- the frame 28 has a column 36 extending outwardly of the two semicircular sections 24 A, 24 B and houses a pinion gear 40 adapted to couple with a suitable drive motor 44 , such as an air motor with suitable gear reduction means.
- the frame 28 is adapted to couple and be fixed relative to a pipe P, and the tool carrier 32 is rotatable relative to the fixed frame 28 and the pipe P.
- the motor 44 is adapted to rotate the tool carrier 32 relative to the frame 28 through a gear train in the column 36 .
- the tool carrier 32 has a circular gear rack 56 for meshing with the pinion gear 40 rotatably mounted in column 36 .
- the pinion gear 40 has an opening 60 provided with a polygonal perimeter for receiving a complementary shaped drive head 64 of drive motor 44 . Therefore, it can be seen that drive motor 44 is adapted to rotate tool carrier 32 relative to the frame 28 through a gear train provided by pinion gear 40 in column 36 and circular gear rack 56 on the tool carrier 32 .
- the rotatable tool carrier 32 includes one or more tool supports 48 (two tool supports shown in the illustrated exemplary embodiment).
- One of the tool supports 48 is used to initially support a laser line generator tool 300 for allowing an operator cutting the pipe to properly place the pipe machining apparatus 20 on the pipe P. Once the apparatus 20 is properly placed on the pipe P, the operator removes the laser line generator tool 300 . Thereafter, the operator inserts cutting or machining tools 52 into the tool supports 48 for performing a cutting or machining operation on the pipe P as the tools 52 rotate circumferentially about the pipe P in a known manner.
- the machining operation performed by the cutting or machining tool(s) 52 may form a straight edge perpendicular to a longitudinal extent of the pipe P, a bevel on an end of the pipe P that is transverse to the longitudinal extend of the pipe P and at an angle other than ninety degrees, or an edge of a pipe P having any angle.
- the tool carrier 32 is rotatably mounted on and supported by frame 28 by a plurality of roller bearings 72 .
- the roller bearings 72 ride in a circular bearing race 76 on the interior of tool carrier 32 .

- the apparatus 20 further includes four adjustable clamp members or coupling members 68 engageable with an exterior of the pipe P and having suitable adjustability to couple and concentrically locate the apparatus 20 to the pipe P when the laser line generator tool 300 is being used as described herein.

- the motor 44 rotates the pinion gear 40 , which, through engagement with the gear rack 56 , causes the tool carrier 32 to rotate relative to the frame 28 and the pipe P.
- the advancement member 84 contacts the advancement projections 80 and rotates as a result, thereby rotating the worm gear assembly 108 .
- Rotation of the feed screw 96 moves the tool clamp 100 and cutting or machining tool 52 toward the pipe P to perform deeper machining into the pipe P.
- the cutting or machining tool 52 advances until the pipe P is machined to a desired extent (e.g., until the pipe is completely cut or parted). After the desired amount of machining is achieved, it may be desirable to retract the cutting or machining tool 52 along the tool support 48 from the advanced cutting position. This can be performed in a conventional manner.
